Charlotte and Her 5 Disciples

Charlotte Eleanor is an Archmage who once saved the world. Using her magic to die, she instead, reverses the age of her body to a young child and starts a second life as Aria Lissen. She had a fulfilling life in her first lifetime, except for one tiny regret. In this new life, Aria is determined to find and live for that one thing she never had... Love. However, she comes to find out that her 'demise' was nowhere as inconsequential to the world as it seemed, and certainly not to her mighty Five Disciples, who aren't coping that well with her loss.
